DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] like Figures 1 to 4 As shown:

[0048] Embodiment 1: The present invention provides an integrated actuator-type thermal management multi-way valve, comprising a multi-way valve mechanism 1 and an actuator mechanism 2;

[0049] The multi-way valve mechanism 1 comprises a multi-way valve body assembly 11, and a valve core assembly 12 is arranged inside the multi-way valve body assembly 11;

[0050] The actuator mechanism 2 includes an actuator protection box assembly 21 installed on the upper side of the multi-way valve body assembly 11, and an actuator assembly 22 is installed inside the actuator protection box assembly 21;

[0051] The actuator assembly 22 can drive the valve core assembly 12 to rotate inside the multi-way valve body assembly 11;

[0052] After the power is turned on, the actuator assembly 22 is controlled to work, and the operation of the actuator assembly 22 drives the valve core assembly 12 to rotate inside the multi-way valve body assembly 11; the rotation of the valve core assembly 12 changes the connection state of the internal flow channel of the multi-way valve, thereby realizing accurate control of the flow direction of fluids such as coolant and heating medium;

[0053] The actuator protection box assembly 21 can protect the integrated actuator assembly 22 .

[0054] Specifically, the actuator assembly 22 includes a driving member 221, a first double gear member 222, a second double gear member 223, a third double gear member 224 and a central gear 225;

[0055] The driving member 221 is fixedly installed inside the actuator protection box assembly 21, and the first double gear member 222, the second double gear member 223, the third double gear member 224 and the central gear 225 are all rotatably embedded inside the actuator protection box assembly 21;

[0056] The central gear 225 is fixed on the valve core assembly 12;

[0057] The driving member 221 can drive the first double gear member 222 to rotate, the first double gear member 222 can drive the second double gear member 223 to rotate, the rotation of the second double gear member 223 can drive the third double gear member 224 to rotate, the rotation of the third double gear member 224 can drive the center gear 225 to rotate, and the rotation of the center gear 225 will drive the valve core assembly 12 to rotate inside the multi-way valve body assembly 11.

[0058] like Figure 4 As shown: Specifically, the driving member 221 includes a motor 2211, and a worm 2212 is fixedly connected to the output end of the motor 2211;

[0059] The first double gear member 222 includes an upper gear 1 2221, and the lower end of the upper gear 1 2221 is fixedly connected to a lower gear 1 2222;

[0060] The second double gear member 223 includes an upper gear 2231, and a lower gear 2232 is fixedly connected to the lower end of the upper gear 2231;

[0061] The third double gear member 224 includes an upper gear 3 2241, and a lower gear 3 2242 is fixedly connected to the lower end of the upper gear 3 2241;

[0062] The worm 2212 and the upper gear 1 2221 are meshed with each other, the lower gear 1 2222 and the lower gear 2 2232 are meshed with each other, the upper gear 2 2231 and the upper gear 3 2241 are meshed with each other, and the lower gear 3 2242 and the central gear 225 are meshed with each other;

[0063] The diameter of the lower gear 1 2222 is smaller than the diameter of the lower gear 2 2232 , the diameter of the upper gear 2 231 is smaller than the diameter of the upper gear 3 2241 , and the diameter of the lower gear 3 2242 is smaller than the diameter of the central gear 225 .

[0064] As can be seen from the above, turning on the motor 2211 can cause the worm 2212 to start rotating. Since the worm 2212 and the upper gear 1 2221 are meshed with each other, the rotation of the worm 2212 drives the upper gear 1 2221 to rotate; then, since the upper gear 1 2221 and the lower gear 1 2222 are fixedly connected, the lower gear 1 2222 will also rotate accordingly;

[0065] The lower gear 1 2222 and the lower gear 2 2232 are meshed with each other, so the rotation of the lower gear 1 2222 will further drive the lower gear 2 2232 to rotate; since the upper gear 2 2231 and the lower gear 2 2232 are also fixedly connected, the upper gear 2 2231 will rotate together with the lower gear 2 2232;

[0066] The upper gear 2231 and the upper gear 3 2241 mesh with each other, which means that the rotation of the upper gear 2231 will drive the upper gear 3 2241 to rotate; similarly, since the upper gear 3 2241 is fixedly connected to the lower gear 3 2242, the lower gear 3 2242 will also rotate together with the upper gear 3 2241;

[0067] Finally, the lower gear 3 2242 and the central gear 225 are meshed with each other, so the rotation of the lower gear 3 2242 drives the central gear 225 to rotate; since the central gear 225 is fixed on the valve core assembly 12, the rotation of the central gear 225 will eventually drive the valve core assembly 12 to rotate inside the multi-way valve body assembly 11;

[0068] In summary, turning on the motor 2211 allows the worm 2212 to drive a series of meshing gears to rotate, and ultimately drives the valve core assembly 12 to rotate inside the multi-way valve body assembly 11 through the central gear 225, thereby achieving precise control of the fluid flow direction.

[0069] As shown Figure 5 As shown:

[0070] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the actuator protection box assembly 21 includes an actuator protection box body 211 and an actuator protection box cover 212, and a gear rod 1 213, a gear rod 214 and a gear rod 3 215 are fixedly installed in the middle of the actuator protection box body 211;

[0071] The first double gear member 222 is rotatably engaged with the outer side of the first gear rod 213 , the second double gear member 223 is rotatably engaged with the outer side of the second gear rod 214 , and the third double gear member 224 is rotatably engaged with the outer side of the third gear rod 215 .

[0072] Specifically, a circuit board 216 is further disposed inside the actuator protection box body 211, and a connector 217 is further fixedly mounted on the outside of the actuator protection box body 211;

[0073] The circuit board 216 and the driving member 221 are electrically connected, and the circuit board 216 and the plug 217 are electrically connected;

[0074] The actuator protection box body 211 is fixedly installed on the upper side of the multi-way valve body assembly 11 , and a sealing ring 1 is also provided between the actuator protection box body 211 and the multi-way valve body assembly 11 . The actuator protection box cover 212 is fixedly embedded in the upper side of the actuator protection box body 211 .

[0075] As can be seen from the above, by rotating and embedding the first double gear member 222 on the outer side of the gear rod 1 213, the first double gear member 222 can stably and smoothly rotate on the gear rod 1 213; similarly, the second double gear member 223 is rotated and embedded on the outer side of the gear rod 214, ensuring the stable rotation of the second double gear member 223 on the gear rod 214; the third double gear member 224 is rotated and embedded on the outer side of the gear rod 3 215, ensuring the stable rotation of the third double gear member 224 on the gear rod 3 215; this design not only improves the stability and reliability of the gear transmission, but also helps to reduce the friction and wear of the gears during the rotation process, thereby extending the service life of the gears; at the same time, the arrangement of the gear rod 1 213, the gear rod 214 and the gear rod 3 215 also provides the necessary support and guidance for the rotation of the gears, making the entire transmission system more compact and efficient;

[0076] In addition, the circuit board 216 disposed inside the actuator protection box 211 is electrically connected to the driver 221, thereby realizing precise control of the driver 221; the circuit board 216 is also connected to an external power source or other control device via a connector 217, thereby facilitating the operation and control of the entire thermal management multi-way valve;

[0077] The actuator protection box body 211 is fixedly installed on the upper side of the multi-way valve body assembly 11, and a sealing ring is provided to ensure the sealing between the two to prevent dust, moisture and other impurities from entering the interior of the actuator, further improving the protection performance of the actuator; the actuator protection box cover 212 is fixedly embedded in the upper side of the actuator protection box body 211, which not only protects the internal components, but also makes the entire actuator mechanism 2 more beautiful and tidy.

[0078] like Figures 6 to 10 As shown:

[0079] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that the multi-way valve body assembly 11 includes a multi-way valve body 111, a plurality of connecting pipes 112 are fixedly mounted on the outer side of the multi-way valve body 111 by screws, and a sealing member 113 is further disposed on the outer side of one end of the connecting pipe 112;

[0080] Specifically, the connecting pipe 112 includes a connecting pipe body 1121, and a mounting plate 1122 is fixedly mounted on the outer side of the connecting pipe body 1121;

[0081] The connecting pipe body 1121 passes through the mounting plate 1122 through a screw rod and is then embedded in the multi-way valve body 111 for positioning.

[0082] Specifically, a limit slot 1123 is further provided at one end of the connecting pipe body 1121;

[0083] The seal 113 includes a seal ring 1131 and a seal ring 2 1132, which are connected via a plurality of short-circuit rods 1133. The seal ring 1131, the seal ring 2 1132 and the plurality of short-circuit rods 1133 are limitedly embedded in the limit card slot 1123 and are formed in one step by injection molding.

[0084] Specifically, the valve core assembly 12 includes a valve core body 121, a connecting column 122 is fixedly connected to the upper end of the valve core body 121, and a partition plate 123 is fixedly installed at the middle position inside the valve core body 121;

[0085] The valve core body 121 is rotatably embedded in the multi-way valve body 111 , and the central gear 225 is fixedly installed on the connecting column 122 . A sealing ring 2 is also sleeved on the outside of the connecting column 122 and is embedded in the middle position of the actuator protection box body 211 .

[0086] As can be seen from the above, through the design of the connecting pipe 112, the multi-way valve body assembly 11 can be conveniently connected to other pipelines or equipment; the connecting pipe 112 includes a connecting pipe body 1121 and a mounting plate 1122, and the connecting pipe body 1121 is inserted into the multi-way valve body 111 through a screw rod to penetrate the mounting plate 1122 and then is embedded in the multi-way valve body 111 for positioning. This installation method is not only firm and reliable, but also easy to disassemble and replace;

[0087] At the same time, the limiting card slot 1123 opened at one end of the connecting pipe body 1121 can accommodate the sealing member 113, and the sealing member 113 includes a sealing ring 1131 and a sealing ring 2 1132, which are connected by a plurality of short-circuit rods 1133, and the limiting card is embedded in the limiting card slot 1123, and is formed by injection molding at one time; this sealing structure can not only effectively prevent fluid leakage, but also improve the stability and durability of the connection;

[0088] The sealing ring 1131 and the sealing ring 2 1132 both adopt a double sealing surface design, which greatly improves the sealing performance against internal leakage and external leakage.

[0089] In terms of the valve core assembly 12, the valve core body 121 is rotatably embedded in the multi-way valve body 111, achieving precise control of the fluid; the central gear 225 is fixedly installed on the connecting column 122, and the sealing ring 2 sleeved on the outer side of the connecting column 122 not only ensures the sealing between the valve core assembly 12 and the actuator protection box body 211, but also plays a role of fixing and supporting; at the same time, the partition 123 fixedly installed in the middle position of the valve core body 121 can separate different fluid channels as needed, further improving the functionality and flexibility of the multi-way valve;

[0090] In summary, the design of the multi-way valve body assembly 11 and the valve core assembly 12 in Example 3 not only improves the connection stability and sealing performance of the multi-way valve, but also enhances its functionality and flexibility, so that the multi-way valve can better adapt to various complex working conditions and fluid control requirements.
